Extremely well done. This nearly approaches art in its execution. Although a trifle, perhaps you should address the strange frameskip between when the old lady walks in and when she makes a shooting motion.

You spent a long time on this? Why does the two floating dots morph into the gun barrel? Why does the background not move? Why does the gun not follow her walking? Why is there a very visible morph between her walking and shooting? Why does it not sync in firefox?
